Description

The present invention relates to a ribbon cassette assembly, a ribbon cassette, and a transfer system consisting of two or more types of ribbon cassettes for storing and holding an ink ribbon.

A transfer system that prints characters or the like on a transfer body such as a card using an ink ribbon is used in various fields. The ink ribbon usually has a strip-shaped ribbon layer (support layer) and an ink layer formed on the ribbon layer and containing a dye or the like. The ink ribbon is generally integrated with the ribbon cassette and incorporated into the transfer system by mounting the ink ribbon cassette composed of the ink ribbon and the ribbon cassette on the transfer system. In printing or printing using an ink ribbon, the ink in the ink layer is transferred to the transfer target by heating with a thermal head.

The ink ribbon cassette is usually formed by fixing one end of the ink ribbon to the supply side bobbin and fixing the other end of the ink ribbon to the take-up side bobbin to store and hold the ink ribbon body in the housing-shaped ribbon cassette. , The ink ribbon and the ribbon cassette are integrated. There are two types of such ink ribbon cassettes, a disposable type and a reusable type. For example, in Patent Document 1, after removing a worn ink ribbon from the ribbon cassette, a new ink ribbon is used as a ribbon cassette. Reusable ink ribbon cassettes that can be stowed are disclosed.
